Test and Research on Anti-lift Properties of Single Pile with Uniform Cross Section

Abstract:

Anti-lift static test was made on single pile with uniform cross section in foundation pits. Strain type steel device was installed on the pile and the strain data on different section in pile were measured successfully. Discussion on value of anti-lift coefficient of test piles, development of lateral friction drag and cracking of concrete pile body were made. The design suggestions about anti-lift piles were given out.

Key words:foundation pits; anti-lift piles; single pile with uniform cross section; anti-lift capacity; lateral friction drag; llong helix bored piles
